I think that marriage was a politcal move by Hillary Klinton to divert attention away from her so she can setup for a POTUS run in 12 for one of two reason, Huma is gay and or a Muzzie.
Plus Wiener wanted to run for Mayor of NY and a wife (who only had to act like she was interested in his personal life) on his arm with connections to the Clinton’s would be a political move on his part.
